Incompatible archive: PCLZIP_ERR_BAD_FORMAT (-10)

In my case this error was not a result of a bug at all. It was because as a few above has said, I had maxed out the storage space on my host. I originally tried to upgrade a wordpress version on https://DailyNewsGuide.com and then I tried to simply upgrade various plug-ins on https://BankFly.com and always received the error above. Going into WHM on hostgator and increasing my packages quote resolved the issue immediately. I wanted to thank everyone on this post for help!

Hello, I had the same problem since 2.8.2, and I solved it by commenting out mbstring.func_overload in my php.ini file:

; mbstring.func_overload = 7

Upgrades and uploads worked perfectly after that.

I can confirm that by increasing the storage limit that error goes away…

cheers!

audioel, where to find php.ini ?

audioel, I annot find php.ini file. Please help me and tell the location of the file. Thanks

ajanini- that was my problem too! Thank you for posting that.
Easy fix and so easy to miss.

I am having the same problem, both with upgrading wordpress and plugins. I have enough space on my server to do the upgrading, but I do not have a ‘php.ini’ file. Would someone please clarify this?

Thanks

Maybe this will help, https://articles.techrepublic.com.com/5100-10878_11-5268948.html?tag=rbxccnbtr1

I simply and successfully manually installed it (ftp folder to plug-ins folder), then avtivated it (using WP ver 2.9.2).

I was able to manually update to WP 2.9.2 on a machine I have local rights to, but then I turned on FTP temporarily and confirmed I could write to the wordpress folders using a stand alone FTP client. The volume has over 40GB free, so it’s not a space issue. I get exactly this under 2.9.2 on said machine:
Downloading install package from https://downloads.www.ads-software.com/plugin/(everything I’ve tried that says it should work w/2.9.2, so far)….
Unpacking the package.
Installing the plugin.
Incompatible Archive
Plugin Install Failed.
Actions: Return to Plugin Installer

my php.ini has already got the line quoted above commented out, assuming that commented out means it has a “;” at the beginning of the line, like all of the other commented out lines… ??

Thoughts all?

I downloaded a zipfile for a new theme I want to add to my WordPress blog. When I go to upload it into WP I get the following message:

Incompatible archive: PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

I am a novice at this stuff so this error message has really thrown me. Thx

SOLUTION – SOLUCIóN

English

I have the solution. Download and decompress the zip file, then recompress [only all files and folders within ZIP file] and upload it to /wp-content/plugins/

ESPA?OL

Descarga, descomprime, comprime, sube, i eso es todo, solo asegúrate de comprimir no una carpeta sino los archivos [y carpetas] que están dentro del archivo ZIP

PD:

At least that worked for me.
Oh, I forgot, do not put special compression features, otherwise the same thing will happen

——-

Al menos eso funcionó para mi.
Ah, me olvidaba no pongan características especiales de compresión, si no ocurrirá lo mismo.

Hi,

For persons getting this error you need to increase the space available to your client on your web server. I had this problem because I had given my client 50 mb and they uploaded a few pictures to their gallery. After I increased the space all issues were resolved

I have 500Mb drive space and 500Mb band width set and am getting this error on 2.92 when I try to update or add a plugin

Incompatible archive PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

I am wondering if it is a server problem. It looks like the error is happening when WP tries to unzip. does WP look for a unzip software on the server? anybody know?

I replaced the http.php file as recommended below but that did not work
